cds-question@unistra.frmolecular-cloudsultraviolet-astronomyspectroscopyWe present results of deep echelle spectrophotometry of the brightest knot of the Herbig-Haro object HH 202 in the Orion Nebula - HH 202-S - using the Ultraviolet Visual Echelle Spectrograph in the spectral range from 3100 to 10400{AA} The high spectral resolution of the observations has permitted to separate the component associated with the ambient gas from that associated with the gas flow. We derive electron densities and temperatures from different diagnostics for both components, as well as the chemical abundances of several ions and elements from collisionally excited lines, including the first determinations of Ca^+^ and Cr^+^ abundances in the Orion Nebula. We also calculate the He+, C^2+^, O+ and O^2+^ abundances from recombination lines.2009MNRAS.395..855Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/395/855CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/395/855https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/395/855http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/395/855https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/395/855https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/395/855http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/395/855GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVOpticaldefaultJ/MNRAS/395/855/table1Identifications, reddening-corrected line ratios [I(Hbeta)=100] for an area of 1.5x2.5arcsec^2^ and heliocentric velocities for the nebular and shock componentsrecnoRecord number assigned by the VizieR team.
